It was a warm summer Sunday afternoon when 13-year-old Jimmy decided to head down to the local park for some outdoor fun. He pedaled his bike, the wind blowing through his short brown hair as he rode.
Arriving at the park, Jimmy noticed a new face - a curvy girl with short blue hair wearing boyish clothes and a backwards baseball cap. She had an androgynous look but Jimmy couldn't help but stare at her thick juicy butt in her tight shorts as she played soccer with some older teenage boys.
Intrigued, Jimmy parked his bike and watched the game. With each kick and run, the girl's voluptuous booty jiggled and bounced hypnotically. She played with the skill and aggression of a tomboy. Jimmy felt himself growing hard watching her.
When the game ended, Jimmy approached the girl shyly. "Hey, I'm Jimmy. Nice moves out there." He tried sounding cool.
The girl flashed a cocky smirk. "Thanks. I'm Jamie. You like watching me play?" She turned sideways, pointing her plump booty towards him as she stretched.
Jimmy gulped, eyes glued to her ass. "Mm-hm. It was hot watching you run around. You've got some serious skills."
"Damn right I do," Jamie said. "Guys usually run that mouth when we're playing, until they see this." She smacked her own big butt and laughed.
Jimmy laughed too, feeling himself stiffen at the lewd display. "Hey Jamie...you want to ditch this lame park and go somewhere private? I want to show you something..."
Jamie looked Jimmy up and down, her blue eyes twinkling mischievously. "Ooh, a secret rendezvous with a cute boy? I'm in."
Jimmy led Jamie behind the park's maintenance shed. "I just wanted to get you alone," he said shyly, "Because you're so gorgeous. And your body...wow."
Jamie smirked, pulling off her baseball cap. "You like my boyish style and girl booty? Most dudes are either intimidated or confused."
"Fuck no, it's so sexy," Jimmy blurted out, face flushing. "Makes me crazy. I'm popping a boner just looking at you."
"Well well, looks like someone's excited." Jamie grabbed Jimmy's bulge, making him gasp. "Damn boy, you're packing some serious heat for a 13-year-old."
Jimmy moaned as Jamie groped him. "Mmm yeah, I'm horny as fuck...I wanna fuck you so bad. Wanna shove my cock in your bubble butt."
"I like the way you think." Jamie yanked down her shorts, revealing her round naked booty. "Come get that ass."
Jimmy hastily pulled out his throbbing erection. He grabbed two big handfuls of booty and plunged his boycock deep into Jamie's tight hole with a groan.
"Ohhh fuuuck," Jamie moaned, arching her back. "That feels so good going in my slutty boy pussy. Pound me with that kid cock!"
Jimmy began to thrust, his short shaft stabbing into Jamie's hot, velvety insides. The forbidden pleasure of fucking an androgynous hottie was overwhelming. He gripped Jamie's wide hips and slammed in balls-deep over and over.
"Ungh yeah, take that dick!" Jimmy grunted, drilling her hard. "Gonna cum so deep in your ass..."
"Give it to me!" Jamie demanded, wiggling her butt on his cock. "Flood my boy pussy with your thick cum..."
"Here it comes!" Jimmy wailed. He gripped Jamie tight and exploded inside her, pumping stream after stream of young jizz deep in her rectum.
"Yes!! Ahh!" Jamie threw her head back, cumming from the anal invasion.
They collapsed together in the grass, panting, Jimmy's softening cock slipping out of Jamie's freshly-fucked hole, cum dribbling out.
"That was so hot," Jamie said breathily. "I'll never forget the time a 13-year-old boy pounded my pussy and turned it into a cum-filled boypussy."
Jimmy grinned, still in awe of her. "Definitely doing that again. And again and again..."
